ABSTRACT
OBJECTIVE: To investigate, through a questionnaire, older adults' demographic and socio-economic characteristics, knowledge, attitudes and practices in terms of food safety and healthy diet; and to develop dietary and hygiene indices able to represent participants' nutritional and food safety behaviour, exploring their association with demographic and socio-economic factors. DESIGN: One-year cross-sectional study. SETTING: Gemelli Teaching Hospital (Rome, Italy). PARTICIPANTS: People aged ≥65 years, Italian speaking, accessing the Centre of Ageing Medicine. RESULTS: Mean age of the sample was 74 (sd 7·7) years. Subjective perception of a safe diet was high: 64·2 % of respondents believed they have a balanced diet. Interviewees got informed about proper nutrition mainly from television, magazines, newspapers, Internet (29·9 %) and from health professionals (34·8 %) such as dietitians, whereas 15·4 % from general practitioners. Regarding food safety, 33·8 % of participants reported to consume expired food, even more than once per month; between 80 and 90 % of participants reported to follow food safety practices during preparation and cooking, even though 49·3 % defrosted food at room temperature. Calculated dietary and hygiene indices showed that the elderly participants were far from having optimal nutritional and food safety behaviours. CONCLUSIONS: These results suggest it is necessary to increase the awareness of older adults in the matter of healthy diet and food safety. Specific and targeted educational interventions for the elderly and their caregivers could improve the adoption of recommended food safety practices and safe nutritional behaviours among older adults.

PURPOSE: The effects of exercise training on neuromuscular function of arm and leg muscles in type 2 diabetic patients (T2D) was investigated. METHODS: Eight T2D sedentary male patients (61.0±2.3years) and eight sedentary healthy age matched control subjects (H, 63.9±3.8years) underwent a 16-week supervised combined endurance and resistance exercise program. Before and after training, maximal isometric (MVIC), isokinetic (15, 30, 60, 120, 180, 240°s(-1)) torque and muscle endurance of the elbow flexors (EF) and knee extensors (KE) were assessed. Simultaneously, surface electromyographic signals from biceps brachii (BB) and vastus lateralis (VL) muscles were recorded and muscle fiber conduction velocity (MFCV) estimated. RESULTS: Following training, maximal torque of the KE increased during MVIC and isokinetic contractions at 15 and 30°s(-1) in the T2D (+19.1±2.7% on average; p<0.05) but not in the H group (+7±0.9%; p>0.05). MFCV recorded from the VL during MVIC and during isokinetic contractions at 15 and 30°s(-1) increased (+11.2±1.6% on average; p<0.01), but in the diabetic group only. Muscular endurance was lower in T2D (20.1±0.7s) compared to H (26.9±1.3s), with an associated increase in the MFCV slope after training in the KE muscles only. CONCLUSION: The effect of a combined exercise training on muscle torque appears to be angular velocity-specific in diabetic individuals, with a more pronounced effect on KE muscles and at slow contraction velocities, along with an associated increase in the MFCV. MFCV appears to be a more sensitive marker than torque in detecting the early signs of neuromuscular function reconditioning.

Aging is characterized by an impaired capacity to maintain the redox balance both in physiological and pathological situations associated with an increased production of reactive oxygen species. Since the extent of this phenomenon may be influenced by an antioxidants-rich diet, we investigated the effect of supplementation with fresh red orange juice (ROJ) on biochemical and cellular biomarkers of oxidative stress in healthy, trained elderly women after a single bout of exhaustive exercise (EE). To this purpose, a sample of 22 females, 15 (69.0 ± 5.1 years) taking the ROJ supplementation and 7 (68.1 ± 2.7 years) as Control group, was constituted. Blood samples were collected immediately before, 30 minutes, and 24 hr after a single bout of EE, at baseline and after 4 weeks. Our results demonstrate that markers of DNA damage or apoptosis were not affected by EE both in Control and ROJ group, and by ROJ, whereas, exercise temporarily affected the redox balance in both groups. Controls didn't change their response to EE after the experimental period, but experimental group after ROJ supplementation had lower EE-induced MDA, consumed less ascorbic acid, and had less activation of the hypoxanthine/xanthine system, i.e., they seemed to be protected from hypoxia/reoxygenation mechanisms.

HYPOTHESIS: Immediate enteral feeding following major abdominal surgery reduces postoperative complications and mortality when compared with parenteral nutrition. DESIGN: A prospective multicenter randomized trial. SETTING: A university hospital department of digestive surgery. PATIENTS AND INTERVENTIONS: Two hundred forty-one malnourished patients undergoing major elective abdominal surgery were randomly assigned to receive, after surgery, either enteral (enteral nutrition group: 119 patients) or parenteral nutrition (total parenteral nutrition group: 122 patients). The patients were monitored for postoperative complications and mortality. RESULTS: The rate of major postoperative complications was similar in the enteral and parenteral groups (enteral nutrition group: 37.8%; total parenteral nutrition group: 39.3%; P was not significant), as were the overall postoperative mortality rates (5.9% and 2.5%, respectively; P was not significant). CONCLUSION: The present study failed to demonstrate that enteral feeding following major abdominal surgery reduces postoperative complications and mortality when compared with parenteral nutrition.

BACKGROUND: The number of hepatic resections for benign and malignant lesions has constantly increased over the past 20 years, as a consequence, surgical experience acquired over the past few years has decreased post-operative morbidity and mortality rates. AIMS: Analysing the relation between potential preoperative risk factors and the occurrence of severe post-operative complications, an attempt is made to identify the variables determining surgical risk in elective hepatic surgery both in normal and cirrhotic liver. PATIENTS AND METHODS: The hospital records of 254 patients who underwent elective liver surgical procedures for hepatic lesions in our department, between 1984 and 1999, were reviewed. The following variables were entered into univariate and multivariate analysis: age, sex, nature of liver lesion (benign or malignant), presence of cirrhosis or cholestasis, synchronous resection of other organs, disorders of blood coagulation, intraoperative blood requirement, the extent of surgical procedures and Pringle's manoeuvre. RESULTS AND CONCLUSIONS: The multivariate analysis of the 254 surgical operations on the liver indicates that the most powerful independent predictors favouring a serious adverse effect includes intra-operative blood transfusions, advanced age and cirrhosis. Scrupulous preoperative clinical evaluation and expert surgical skills minimize intra-operative bleeding and proved to be the most significant factors influencing morbidity and mortality rates.

The major determinants of the poor prognosis of the patients with proximal-third gastric cancer (proximal gastric cancer or PGC) when compared with that of patients with more distally located gastric tumors (distal gastric cancer or DGC) rely both on the more advanced age and tumor stage at the moment of clinical presentation and on the higher postoperative mortality for PGC patients. We reviewed hospital records of 707 patients with gastric cancer (187 with PGC and 520 with DGC) observed during the period 1981 through 1996 at the same surgical unit. Demographic and pathological data, type of treatment, and hospital morbidity and mortality rates were recorded. Univariate and multivariate survival analysis was used to calculate the 5-year survival probabilities with respect to the following clinical and pathological variables: age, sex, gross appearance according to Borrmann classification, histological type according to Lauren, stage of the disease, tumor location, and type of treatment. PGC was associated with more advanced tumor stage (P < 0.0001), older age (P = 0.039), and higher necessity of extended surgery (P < 0.0001) when compared with DGC. Hospital mortality was 9.6 and 5 per cent in PGC and DGC patients respectively (P = 0.033). Overall 5-year survival was 17.7 and 36.4 per cent in PGC and DGC patients (P < 0.0001): 35.9 versus 57.6% (P = 0.0001) and 3.7 versus 7.6 per cent (P = 0.03) after radical and palliative surgery respectively. At multivariate survival analysis proximal location was found to be independently associated (P = 0.0007) with poor survival. The multivariate model shows the proximal location as an independent predictor of lesser favorable outcome in gastric cancer. The major determinants of the poor prognosis of PGC with respect to DGC rely both on the more advanced age and tumor stage at the moment of clinical presentation and on the higher postoperative morbidity for PGC patients.

OBJECTIVE: To evaluate whether the excess mortality in men with AD can be explained by a gender difference in the predictors of mortality. METHODS: The authors studied 2,838 men and 6,385 women over 65 years of age with AD admitted, between 1992 and 1995, to 1 of nearly 1,500 nursing homes in five U.S. states (Kansas, Maine, Mississippi, New York, and South Dakota). Resident level data including sociodemographic characteristics, dementia severity, measures of physical disability, comorbidity, and other clinical variables were collected with the Minimum Data Set. Information on death was derived through linkage to Medicare enrollment files; the median follow-up was 23 months. Baseline characteristics were used to predict age at time of death in Cox proportional hazard models. RESULTS: Men with AD had an increased risk of mortality relative to women, adjusted for differences in the distribution of age and race. The most important predictors of death in men were those related to the disease itself. These were the severity of dementia and the occurrence of episodes of delirium. Instead, death among women was associated with measures of disability, namely, impairment in performing the activities of daily living, presence of pressure sores, malnutrition, and comorbidity. CONCLUSION: These data suggest that the underlying mechanisms for AD may be different in men and women. Future studies of survival and progression of AD need to examine men and women separately.

BACKGROUND: Tumour necrosis factor-alpha (TNF) has been regarded as a potential mediator of cancer cachexia. Assessment of TNF circulating levels in cancer patients and their correlation with weight loss has led to controversial results. MATERIALS AND METHODS: We measured TNF circulating levels in 28 patients with gastrointestinal cancer and 29 controls with benign gastrointestinal diseases at different times (08.00 h, 14.00 h, 20.00 h) before operation. RESULTS: TNF activity was not detected in any of controls at any times. In cancer patients, TNF circulating levels were detectable in 18 cases (64.3%) and appeared to be discontinuous. TNF levels above the limit of detection were present in 15 patients (53.6%) at 08.00 h, in 14 (50%) at 014.00 h and in nine (32.1%) at 20.00 h. Mean TNF levels were 14.3 +/- 4 pg mL(-1) at 08.00 h, 16.7 +/- 4.6 pg mL(-1) at 14.00 h (P = 0.05) and 18.5 +/- 10.2 pg mL(-1) at 20.00 h (P < 0.05 vs. 08.00 h and 14.00 h). According to Spearman's analysis, the sum of TNF concentrations at the three times significantly correlated with the severity of weight loss (Spearman's correlation coefficient = - 0.420; P = 0.026). TNF concentrations were consistently and significantly higher in patients with severe weight loss than in those with moderate or light weight loss at 08.00 h (26.3 +/- 8.3, 8.9 +/- 4.2, 3.8 +/- 2.1, respectively; P = 0.04 at one-way ANOVA). TNF levels were higher in anorectic than in nonanorectic patients at any hour, but the differences were not statistically significant. CONCLUSIONS: The present study demonstrates that TNF is intermittently or discontinuously detectable in patients with gastrointestinal cancer and that its levels correlate with the severity of weight loss.

OBJECTIVES: To quantify the impact of legislation on nursing home residents, psychotropic drug use, and the occurrence of falls in the US compared with five countries with no such regulation. DESIGN: A retrospective cross-sectional study SETTING: Nursing homes in five US states and selected nursing homes in Denmark, Iceland, Italy, Japan, and Sweden. PARTICIPANTS: Residents in nursing homes in five US states and the aforementioned countries during 1993-1996. MAIN OUTCOME MEASURES: Using data collected using the Minimum Data Set, logistic regression provided estimates of the legislative effects on the use of antipsychotics and antianxiety/hypnotics while simultaneously adjusting for potential confounders. The occurrence of falls was evaluated similarly. RESULTS: Prevalence of antipsychotic and/or antianxiety/ hypnotic use varied substantially across countries. After adjustment for differences in age, gender, presence of psychiatric/neurologic conditions, and physical and cognitive functioning, residents in Denmark, Italy, and Sweden were at least twice as likely to receive these drugs (Denmark Odds Ratio (OR)=2.32; 95% Confidence Intervals (CI), 2.15-2.51; Italy OR=2.05; 95% CI, 1.78-2.34; Sweden OR=2.50; 95% CI, 2.16-2.90); in Iceland, the risk was increased to greater than 6 times (OR=6.54; 95% CI, 5.75-7.44) that of the US. Residents were less likely to fall in Italy, Iceland, and Japan compared with the US, despite more extensive use of psychotropic medication, whereas residents in Sweden and Denmark were more likely to fall. CONCLUSIONS: Policy has had an impact on the prescribing of psychotropic medication in US nursing homes compared with other countries, but it is unclear if this is translated into better outcomes for residents.

Benzodiazepine use is a well-identified risk factor for falls and the resulting femur fractures in elderly adults. Benzodiazepines not requiring hepatic biotransformation may be safer than agents undergoing oxidation because oxidative activity has been shown to decline with age. The association between the use of either oxidative or nonoxidative benzodiazepines and the risk of femur fracture among elderly adults living in nursing homes was studied. A nested case-control study was conducted using the Systematic Assessment of Geriatric drug use via Epidemiology (SAGE) database; the records of 9,752 patients hospitalized for incident femur fracture during the period 1992 to 1996 were extracted, matching by age, gender, state, and index date to the records of 38,564 control patients. Conditional logistic regression models were conducted to estimate the odds ratios (ORs) for femur fracture with adjustment for potential confounders. The adjusted OR for the overall use of benzodiazepines was 1.10 (95% confidence interval [CI], 0.98-1.20); the risk seemed of only slightly greater magnitude for exposure to nonoxidative agents (1.18; 95% CI, 1.03-1.36) than to oxidative benzodiazepines (1.08; 95% CI, 0.95-1.23). Among the latter, the effect was mainly accounted for by the use of agents with a long elimination half-life. A dose relationship was observed exclusively among users of long half-life oxidative benzodiazepines. The risk associated with the use of nonoxidative benzodiazepines showed no relationship to the age of the patients. In contrast, patients aged 85 years or older receiving oxidative benzodiazepines at high dosages or as needed had a two- to three-fold increased risk of femur fracture than did patients in the younger age group. Among older individuals, the use of benzodiazepines slightly increased the risk of femur fracture, mainly irrespective of the metabolic fate of the drug. Our results suggest that the use of nonoxidative benzodiazepines does not carry a lower risk for femur fracture than does the use of oxidative benzodiazepines. However, the latter agents may be associated with a somewhat higher risk of side effects among the oldest old, especially at higher dosages.

BACKGROUND: Early diagnosis of dementia is critical, but there is usually a time lag between onset of symptoms and referral for neuropsychological testing and dementia diagnosis. We aimed to identify factors correlated with this delayed referral. METHODS: We studied 140 patients with cognitive deterioration referred to the Memory Clinic of the Catholic University (Rome) between 1995 and 1996. Alzheimer's disease or multi-infarct dementia was diagnosed according to National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria and Hachinski ischemic score. Global cognitive and neuropsychological functions were assessed with the Mini-Mental State Exam (MMSE) and the Mental Deterioration Battery. The performance on the Activities of Daily Living was used to measure physical function. The time between onset of signs of cognitive deterioration and referral for diagnosis (time to diagnosis: TTD) was estimated through a semistructured interview of the caregiver. Independent correlates of TTD were identified after adjustment for potential confounders and stratifying patients based on level of physical function. RESULTS: Of 127 eligible patients, 63% had Alzheimer's disease, 26% multi-infarct dementia, and 11% had dementia of other types. Mean age was 73.9 +/- 8.2 years, and 59% of patients were females. The mean TTD was 13.8 +/- 10.8 months and did not differ by gender, household composition, or type of dementia. For patients with normal physical function, increased age (beta = .50), female sex (beta = .51), and low MMSE score (beta = .36) were associated with longer TTD. Among patients with physical impairment, only MMSE score showed an association with TTD, but it was of opposite direction (beta = -.31). These associations were consistent by type of dementia. CONCLUSIONS: Age, gender, and degree of cognitive impairment are important correlates of the time between onset of signs/symptoms and referral for dementia diagnosis. These factors are independent of the type of dementia but are influenced by the level of physical function.

The hospital records of 639 patients affected by primary gastric cancer who were consecutively admitted to our unit during the period 1981-1995 were reviewed. Overall 220 underwent total gastrectomy (38 palliative), 12 had resection of the gastric stump, 195 had distal subtotal gastrectomy (55 palliative), 78 had bypass procedures, 72 had explorative laparotomy, and 62 had no operation. Univariate and multivariate analyses were used to evaluate 5-year survival with respect to the main clinical, pathologic, and treatment variables after both curative and palliative treatments. Overall the 5-year survival after curative treatment (320 patients-operative mortality excluded) was 55.5%: 91.1% for stage IA, 71.5% IB, 62.4% II, 37.5% IIIA, 31.5% IIIB. Among patients who underwent palliative treatment 5-year survival was 13.1% after gastric resection (total or distal subtotal), 4.9% after the bypass procedures, 0 after explorative laparotomy, and 0 after no operation. Univariate and multivariate survival analyses showed that variables independently associated with poor survival were advanced stage, upper location and D1 lymphadenectomy after curative treatment, tumor spread to distant sites, and nonresectional surgery after palliative treatment. Multivariate analysis showed that even though survival with gastric cancer depends on predetermined factors, the type of surgery can have a significant effect on prognosis after both curative and palliative treatment.

BACKGROUND: Randomized trials have shown that angiotensin-converting enzyme (ACE) inhibitors reduce mortality and morbidity, and improve symptoms and exercise tolerance in selected patients with congestive heart failure (CHF). There is, however, no evidence on the effectiveness of ACE inhibitors in the typical, very old and frail patients with CHF. OBJECTIVE: To compare the effects of ACE inhibitors and digoxin on 1-year mortality, morbidity, and physical function among patients aged 85 years. METHODS: We conducted a retrospective cohort study using the SAGE database, a long-term care database linking patient information with drug utilization data. Among 64637 patients with CHF admitted to all nursing homes in 5 states between 1992 and 1995, we identified 19492 patients taking either an ACE inhibitor (n = 4911) or digoxin (n = 14890). Record of date of death was derived from Medicare enrollment files, and we used the part A Medicare files to identify hospital admissions and discharge diagnoses. As a measure of physical function, we used a scale for activities of daily living performance. The effect of ACE inhibitors was estimated using Cox proportional hazards models with digoxin users as the reference group. RESULTS: The overall mortality rate among ACE inhibitor recipients was more than 10% less than that of digoxin users (relative rate, 0.89; 95% confidence interval, 0.83-0.95). Mortality was equally reduced regardless of concomitant cardiovascular conditions and baseline physical function. Treatment with ACE inhibitors was associated with a tendency toward reduced hospital admissions that was more evident among patients with greater functional impairment. The adjusted relative rate for hospitalization for any reason was 0.96 (95% confidence interval, 0.91-1.01). The rate of functional decline was greatly reduced among ACE inhibitor recipients (relative rate, 0.74; 95% confidence interval, 0.69-0.80), and this effect was consistent and independent of background comorbidity and baseline physical function. CONCLUSIONS: These data suggest that survival and functional benefits of ACE inhibitor therapy extend to patients with CHF 85 years and older, and mostly women, both systematically underrepresented in randomized trials. Alternatively, digoxin has a detrimental effect in this population.

BACKGROUND: Increasing prevalence, use of health services, and number of deaths have made congestive heart failure (CHF) a new epidemic in the United States. Yet there are no adequate data to guide treatment of the more typical and complex cases of patients who are very old and frail. METHODS: Using the SAGE database, we studied the cases of 86,094 patients with CHF admitted to any of the 1492 long-term care facilities of 5 states from 1992 through 1996. We described their clinical and functional characteristics and their pharmacologic treatment to verify agreement with widely approved guidelines. We evaluated age- and sex-related differences, and we determined predictors of receiving an angiotensin-converting enzyme (ACE) inhibitor by developing a multiple logistic regression model. RESULTS: The mean age of the population was 84.9 +/- 8 years. Eighty percent of the patients 85 years of age or older were women. More than two thirds of patients underwent frequent hospitalizations related to CHF in the year preceding admission to a long-term care facility. Coronary heart disease and hypertension were the most common causes. Half of the patients received digoxin and 45% a diuretic, regardless of background cardiovascular comorbidities. Only 25% of patients had a prescription for ACE inhibitors. The presence of cardiovascular comorbidity, already being a recipient of a large number of medications, a previous hospitalization for CHF, and admission to the facility in recent years were associated with an increased likelihood of receiving an ACE inhibitor. The presence of severe physical limitation was inversely related to use of ACE inhibitors, as were a series of organizational factors related to the facilities. CONCLUSIONS: Patients in long-term care who have CHF little resemble to those enrolled in randomized trials. This circumstance may explain, at least in part, the divergence from pharmacologic management consensus guidelines. Yet the prescription of ACE inhibitors varies significantly across facilities and depends on organizational characteristics.

BACKGROUND: Optimal care for frail elderly patients depends on comprehensive assessment. This is especially true in the complex setting of interdisciplinary home care programs. To facilitate comprehensive assessment, as well as to generate a useful, policy-relevant patient database, standardized, multidimensional, and validated instruments are very helpful. OBJECTIVES: The aim of the present study was to demonstrate that the Minimum Data Set assessment instrument for Home Care (MDS-HC) can be used to detect functional and cognitive impairment as defined by analogous research instruments. RESEARCH DESIGN: This was a cross-sectional correlation study. SUBJECTS: We studied 95 patients admitted to home care services of the Health Care Agency of Bergamo (Italy). MEASURES: The MDS-HC form was completed for all patients by well-trained nurses, independently of and with nurses blinded to the results from the research rating scales. The Barthel Activities of Daily Living (ADL) Index, the Instrumental Activities of Daily Living of Lawton (IADL), and the Mini Mental State Examination (MMSE) were considered the gold standard. RESULTS: Agreement between the MDS-HC scales and the research rating scales was assessed with Pearson's correlation coefficient. This coefficient was 0.74 for MDS-ADL versus Barthel Index, 0.81 for MDS-IADL versus Lawton Index, and 0.81 for Cognitive Performance Scale versus MMSE, indicating an excellent agreement. CONCLUSIONS: The MDS-HC scales, when performed by trained nurses using recommended protocols, provide a valid measure of function and cognitive status in frail home care patients. These findings point out the overall validity of the functional and clinical data contained in the MDS-HC assessment. Use of the MDS-HC gives the unique opportunity of setting up a database, a prerequisite for all epidemiological evidence-based medicine studies.

Home care programs for the treatment of frail elderly have been developed in many countries around the world. In the Silver Network project all services are provided in an integrated fashion by one "single entry" center, differently from the traditional fee-for-service or not integrated systems. The delivery of health and social services for frail elderly individuals are integrated and coordinated by a case manager who uses a "second generation" assessment instrument, the Minimum Data Set for Home Care (MDS-HC). We describe the principal clinical and functional characteristics of nearly 1300 patients admitted between 1997 and 1998 to such an integrated home care program in eleven Italian Health Agencies. The database, derived from the serial MDS-HC assessments of each patient, provides a unique opportunity to delineate the different criteria for eligibility for home care, and compare the selected populations of the participating Health Agencies.

OBJECTIVE: To investigate whether differences in the number and type of comorbid conditions may help explain the gender gap in mortality among patients with AD. BACKGROUND: The prevalence and incidence of AD are higher among women, who also have more severe cognitive impairment and accelerated decline. However, men have an exceedingly higher mortality. METHODS: The authors conducted a retrospective cohort study on 5,831 men and 17,918 women with a diagnosis of AD. Data were from the Systematic Assessment of Geriatric drug use via Epidemiology (SAGE) database, which includes information on residents of 1,492 nursing homes in five US states (1992-1995). Men and women were compared with respect to demographic characteristics, dementia severity, psychiatric and behavioral symptoms, indicators of physical disability, and general health status. Also compared were age- and race-adjusted prevalence of all comorbid conditions at each level of cognitive impairment. In survival analyses, the risk of death and of hospitalization were determined by gender and level of cognitive impairment. Finally, gender-related differences in the intensity of pharmacologic treatment were examined. RESULTS: Women were older than men (83+/-7 versus 81+/-7 years) and were more likely to exhibit severe cognitive deterioration (27% versus 19% among men). Overall, there were no significant gender-related differences on several measures of physical disability (activities of daily living performance, gait and history of falls, incontinence, pressure sores), but significantly more women were underweight (45% versus 37% among men). However, the age- and race-adjusted 1-year mortality rate was 17% for women and 31% for men. The mortality rate of women at the highest degree of dementia severity was lower than the rate for men with minimal cognitive impairment. At any level of cognitive impairment, the prevalence of arrhythmia, chronic obstructive pulmonary disease, PD, and cancer was higher among men. Women were also less likely to be hospitalized, and they received fewer medications for each given disease. CONCLUSIONS: The survival advantage of women with AD relative to men may occur as a result of fewer comorbid clinical conditions associated with the diagnosis of dementia.
